Bella Thorne vs. Zosia Mamet: The Stars Battle It out with Stylish Buns

These topknots are top-notch, but whose 'do is best?

What's the one thing you're bound to see at fashion week? Among the super chic editors, ahead-of-the-trend bloggers, and stylish A-list stars that dominate the front rows of the season's hottest shows, you'll inevitably spot tons of topknots. Not only is this no-fuss hairstyle a quick and easy antidote to awkward hair days and end-of-summer humidity, but it also instantly adds a certain cool factor to any look. Bella Thorne was a bunhead at the Nicole Miller show, and Zosia Mamet wore a classic version of the coif to Rebecca Minkoff's spring runway.

Bella's poof is totally cute, but it's her thick, peek-a-boo bangs that make this 'do a mane attraction! Her smooth, shiny strands add polish to the low-key style, and we're loving how her wispy fringe and tendrils keep things casual. To finish off her show-going look, she's rocking peachy lip gloss and a hint of turquoise eyeshadowcomplementing her colorful statement necklace perfectly.

With not a loose strand in sight, Zosia's sporting a more traditional take on the topknota 'do her Girls character Shoshonna would heartily approve of. The result is sleek and sophisticated, but not too fancy, since her natural waves create a little bit of chic volume and dimension. Completing her look with navy eyeliner (which cleverly matches her luxe moto jacket) and a pastel pink pout, she's got plenty of downtown style cred, but with some girly sweetness, too.
